I was playing through The Last of Us recently, when it dawned on me.....the true irony. Her favorite game is called the turning, and at the end of Left Behind she has turned. I dont know about anyone else but I find this highly ironic.

There are lots of heavy-booted easter eggs, hints and foreshadowing-by-hindsight things like that in TLoU.

FWIW, I also think that Neil considers the Twilight saga to be one of the signs of the end of the world, given that its in-universe equivalent had just come out in theatres at the time of the Outbreak! ;-)
